Lets dig a little deeper on two impressive races:

Overall, the Men's 100 Fly finished 0.75s faster in 2018, with only 0.6s separating 2nd and 8th, where 2017 had ~2s separating the field

There was significant movement across all metrics year over year, even if we ignore the Dressel factor.

Fig 1. Total Time Underwater

Fig 2. Stroke Rate by Split

Fig 3. Average Stroke Counts per Length

The three most changed metrics from 2017 to 2018 were Time Underwater (Fig. 1), Stroke Rate (Fig. 2), and Stroke Count (Fig. 3). See our analysis of each below.

Note: there were only 7 finishers in 2017, as Lane 7 was DSQ in the race

Time Underwater:

As shown by the graph of Total Time Underwater (Fig. 1), Time Underwater increased across most of the field

More than half of the 2017 competitors went shorter than 18 s total time underwater, while in 2018 everyone remained under for at least 18s

The average competitor in 2018 stayed under 8% longer, with the middle 2 competitors just behind average at 7.8%

Stroke Rate (Cycle Time):

As shown in the graph of Stroke Rate above (Fig. 2), cycle times on average got faster in 2018, with significant changes on the 2nd and last splits

The average slowed down by 2.5%, but the middle saw less fluctuation at 1.4%

The slowest Stroke Rate slowed by 0.1 s/cycle

Stroke Count

In Fig. 3 above, we can see stroke counts decreased for most athletes in 2018

Stroke count decreases seem to be related for the most part to time underwater increases

Total range of stroke counts in each length decreased since no swimmer averaged more than 6 strokes per length in 2018

DPS:

The 2018 field is more condensed, reducing the longest strokes by ~0.2 m and increasing the shortest by 0.4 m

2018 saw one outlier at the front of the field (Dressel), where 2017 had one outlier significantly behind the field

Average field dropped 0.1%, but middle increased by 0.3%

Stroke Index

Majority of field produced less efficient strokes in 2018

Swimmers increased their stroke index, particularly in the first split, where the average Stroke Index increased from 4.5 to 4.9

Overall average is up 0.6%, but middle group only up 0.3%

Women's 100 Breaststroke

2018 saw a far more dispersed field overall in theWomen's 100 Breaststrokerace, with nearly 4 s separating 1st from 8th, but only 1 s separating 2nd from 7th.

Several metrics saw some shifting year over year in the Women's 100 Breast, while others remained quite similar. Also Lilly King put in a great performance, with many of her individual metrics making noticable moves

Fig 1. Total Time Underwater

Fig 2. Stroke Rate by Split

Fig 3. Average Stroke Counts per Length

The most changed metrics from 2017 to 2018 were Time Underwater (Fig. 1), and Stroke Rate (Fig. 2). See our analysis of each below.

Time Underwater:

In Fig. 1 above, we see an almost small average increase in time spent underwater in 2018 (half a second longer)\

The longest total Time Underwater rose by 0.6s while the shortest also rose a similar amount, by 0.5s

Top four finishers in 2018 held very similar total time underwater near 19 s

Stroke Rate (Cycle Time):

Similar to the Men's 100 fly, stroke rates were slower across all splits, as seen in Fig. 2 above

This slow down included Lilly King, whose stroke rates slowed compared to last year

Stroke rate changes occurred in the first splits of the race, but the last split remained similar to last year

Stroke Count

in Fig. 3 above, we saw no significant shift in stroke counts for most swimmers

Lilly King fit almost a full extra stroke into each of her lengths this year compared to her stroke count last year

This extra stroke slightly increased the range of stroke counts we saw

DPS:

Shortest DPS of the 2018 field pulled 0.1 m longer strokes than in 2017

Average competitor lengthened their stroke by 0.6%, where middle 2 competitors shorted by 0.6%

Longest DPS saw basically 0 movement year over year

Stroke Index

Overall field relatively stable year over year, with an average increase of 0.2%

The middle 2 competitors in 2018 increased their efficiency by 0.2

The range between the top and bottom performer decreased in 2018 by 0.1
